It's all kicking off in The Tunnel this evening. A tense chase ends with the French secret service capturing prime suspect Fabien Vincent, but disaster strikes when he escapes and Elise subsequently disappears. Karl searches Danny's flat for personal links to the Truth Terrorist and discovers the journalist was harbouring a secret connecting him to the mysterious death of the family of an undercover policeman who the detective used to work with. The plot thickens... but if you've seen the Danish original you might just know where it's going.
